While I love that the Naturalico Eye Serum has both vitamin C & E in it, it really only works best at night because of the vitamin E. I found that when I used the product under my makeup it caused my foundation powders to flake throughout the day. I also found my skin to feel a little more greasy than normal.
The Naturalico Eye Serum product comes in a tinted bottle to keep sun light out so it won't jeopardize the quality of the product inside the bottle. The eye dropper is easy to use and it helps keep the air out. I typically use a few drops in between two fingers and I massage the product in a circular motion under my eyes. Try not to pull too hard on your skin because over time this area loses elasticity and the pulling can create more loose skin or bags under your eyes. If you're worried about pulling the skin try patting the product on gently with a makeup sponge.
